OS X (MacOS) message:iToolBox can't be opened because it is from an unidentified developer

In this case, OS X (MacOS)'s Gatekeeper security mechanism is preventing you from opening iToolBox.

To resolve this, the first time you open iToolBox after a new download, instead of opening iToolBox with a double-left-click or a left-click on the icon in the dock, open it by right-clicking on the application icon and selecting Open from the OS X (MacOS) context menu.

You will then be asked if you want to open the application anyway; go ahead and do so. Apple is trying to protect you from malware with this intentional impediment to opening unsigned applications.

Why isn't iToolBox signed?

Because it is free. Apple demands $99.00 USD per year to enable application code signing. Consequently, you get to work your way around Gatekeeper. There is some risk in this; it is theoretically possible for a bad actor to intercept your download, modify the application on its way to you, and so manage to insert malware into your system.

OS X (MacOS) crash after agreeing to let iToolBox request a serial number

At the time of this writing, I have one report of an OS X (MacOS) 10.13.6 system that crashes when network operations are instantiated, while at the same time, numerous 10.13.6 systems are not having problems. If this happens to you, restart iToolBox, say NO when asked if it's okay to request a serial number, and iToolBox will not undertake any network operations. This should work around the issue.

This message is encountered when an attempt is made to open iToolBox on a version of OS X (MacOS) that is too old to run the application. The only solutions to this are to either install a newer OS X (MacOS) in a VM, upgrade your primary version of OS X (MacOS) to a more recent version, or, if your hardware/VM does not support a more recent version of OS X (MacOS), to move to a newer Mac or more capable VM. iToolBox requires at least OS X (MacOS) 10.11.
